Use XDamageReportNonEmpty instead of XDamageReportRawRectangles.
In XDamageReportNonEmpty mode the server generates a single damage
event when the damage state transitions from not-damaged to damaged.
When the compositor is ready to paint the screen, it requests the
damage region for each window and resets the state to not-damaged.
With XCB we can request the damage regions for all windows in a
single roundtrip, making this the preferred mode.
This should reduce the number of wakeups and the time spent
processing damage events between repaints.

apparently selectionChanged signal is not sent by Qt.

It appears that we're accidentally choosing an MSAA config with the
Intel driver in Mesa 9.0. So change the algorithm to take the values
of GLX_SAMPLES and GLX_SAMPLE_BUFFERS into account.
Found by Kenneth Graunke.
According to Pierre-Loup Griffais (Plagman on IRC) this is causing
choppy VDPAU video playback when compositing is enabled.
Removing these calls doesn't seem to cause any regressions, and the
commit that added them doesn't give a reason. So let's just get rid
of them for now.

Boxswitch is activated as tabbox, possibly due to a downstream issue
This results in multiple effects being assigned to the tabbox and no
GUI way for the user to fix this.
Since the BoxSwitch effects nowadays only exists as sidearm for
coverswitch, the tabbox setting is now hardcoded and disabled in the
effect, making it completely impossible to accidentally use it as tabbox.

Adjustment to reality. KWin has had a dependency on Mesa 8.0 for quite
some time given that it is what basically all distributions ship.
It is better to clearly state what is required. For KWin Mesa 8.0 is a
more reliable dependency as all DRI drivers which do not support DRI2
have been removed.
Packagers have been informed about this intended change some weeks ago.
